I'm going to say Tiwanaku
Yep... It's probably the last South-American I'll make for now (I still have other 3 in store, an indigenous and a modern, but its time to focus on the announced ones), before heading north for central and north American civs...
I decided to make it as it's perhaps one of the few of that region and age that has a named leader (unlike the Nazca or the Wari), I recently read some info on it, and the leader is Huyustus, who divided the Andean region in four reigns (later used as a base for the Inca). He's also shrouded in myth though, as the myths say that he took his people to the Kingdom of Stars, to explain the apparent dissapearance of Tiwanaku's people...
That symbol at the back is almost exactly the same as the Aymara/Qullana icon.
Which is why I had to change it. The Aymara, the Inca (both which formed the Qullana Confederation after the Colony) and the Mapuche (and all of the cultures in the Andean Region) inherited a lot from both Wari and Tiwanaku, and the Chakana (the symbol) and religious symbols were specially developed in Tiwanaku.
The reason I'm making them is mostly because their influence plays a huge role in the post-colonial times. As many cultures started tracing back their roots to the Chakana symbol, and started using it as a ways of protest against Modern Countries, specially in Bolivia.
So yeah... They'll be a Faith-Science oriented civ, with strong Tourism in the end as a nod of their cultural influence throught the Andes, still building up the details. But this is a rough sketch of them:
Tiwanaku Civilization
UA: ?
UU: Amauta: Replacement for both the Great Scientist and Great Prophet, so may be adquired through Scientist specialists and through Faith. May spread religion, discover a technology, or build a Solstice Holy Site.
UB: Solstice Gate: Replacement for the Library. Grants Faith aside from Science. Generates Tourism after Archaeology is discovered.

For now no more civs will be announced, at least until 3 of the announced ones get finished, right now we have the following in the WIP space:
- Argentina: The Leaderhead needs some tweaks, lacks icons... As the Tango Hall will likely replace the Musician's Guild in BNW, can't be finished just yet. Testing out ways of working out the Descamisado's Great Person generation.
- Mapuche: Leaderhead and Icon done. Waiting for the announcement of the last BNW civs in hopes for an interesting mechanic that could work for the Mapuche, and for a Farm Bug Fix whether by Ekmek or Firaxis.
- Chile: Leaderhead in process. This one could get out without the need of BNW, so might be done before July.
- Tupi: Leaderhead in process. Waiting for a Farm Bug Fix.
- Tiwanaku: Leaderhead done. Working out on the details of the civ.
